"From the first call to the final cleanup, the process was seamless. They provided a same-day estimate and had our new roof installed just a few days later. The crew was fast, professional, and left our property spotless. Highly recommended!"

Systems

Common Flat Roofing Systems

Our commitment is to install a roofing system that perfectly matches your facility's requirements. The ideal choice is based on a careful evaluation of your budget, operational demands, and long-term performance goals.


🛠️ TPO (Thermoplastic Olefin)


A leading choice for energy efficiency and performance. TPO's highly reflective surface deflects solar radiation to help lower cooling expenses. Its seams are heat-welded to create a strong, continuous membrane, offering superior protection against leaks.


🛠️ EPDM (Ethylene Propylene Diene Monomer)


A time-tested synthetic rubber roofing membrane renowned for its proven durability and impressive service life. It is engineered to withstand severe weather, offering excellent resistance to UV exposure, hail, and extreme temperature changes, making it a consistently dependable, low-maintenance solution.


🛠️ Modified Bitumen


Engineered for maximum toughness, Modified Bitumen is a robust, multi-ply system that provides exceptional resistance to punctures and tears. Its durable, asphalt-based composition makes it the ideal choice for roofs with high foot traffic or a large number of penetrations, offering multiple layers of waterproof protection.

FAQ's

Frequently Asked
Questions

Here you’ll find a compilation of the most frequently asked questions. If there’s something you want to know which isn’t here, please send an email to office@threesonsroofing.com.

Why do so many buildings choose flat roofing?

Flat roofs are budget-friendly and practical. In Oahu, they make solar panel installs easier. In Delmarva, they allow for efficient HVAC setups even with strong seasonal winds.

How long does a flat roof usually last?

With proper care, flat roofs often last 20–25 years. Oahu’s UV rays can shorten that if not maintained. Delmarva roofs, withstanding snow and storms, last longer with regular inspections.

Do flat roofs need special maintenance?

Yes. Oahu’s tropical rains make regular drain checks crucial. In Delmarva, snow and ice must be cleared to prevent excess weight or water pooling.
